Hello! I am trying to retrieve the standard deviation value from a detector viewer via the use of a NSDD operand #Pix -4 . How might I do so?
Thanks.

Hi Kai,
The Help File about NSDD can be found under The Optimize Tab (sequential ui mode) > Automatic Optimization Group > Merit Function Editor (automatic optimization group) > Optimization Operands by Category > Non-sequential Ray Tracing and Detector Operands.
In short, prior to calling any subsequent NSDD operand, you need a call to a NSDD which clears all detectors. Since all detectors need to be cleared, you also need to run a raytrace. In your Merit Function you should have:
I’ve shown an example in the screenshot below:
For the standard deviation you need to specify the Det#, 2 in my case, the Pix#, -4 as you mentioned, and the Data is 0 for flux, 1 for flux/area, 2 for flux/solid angle pixel, 3 for normalized flux, 4 for absorbed flux, and 5 for absorbed flux/area.
Does that make sense?
Take care,
David
